I have a 20 gallon tank. currently doing a fishless cycle..which is now almost 2 months in the making. I wanted to better filter vs the one that came with the kit i bought.
So- Purchased the marineland power filter penguin 200 for up to 50 gallons.
question 1: Why wont it work???? I hooked everything up the way the directions say and only get fizzy bubbles by the intake tube. biowheel not moving.
question 2: Does it matter which way the mid level intake strainer is connected.. the directions dont give a clear desciption of how it should be connected to the intake tube.
question 3: I dont want to loose beneficial bacteria so how do i minimize this with getting a new filter?
question 4: can i or should i add the old carbon filter to the new filter even though its smaller? or should i run 2 filters?
